Preferably, the reinforcing rib plate is formed by arranging a plurality of layers of horizontal baffles along the filter plate and arranging a plurality of vertical baffles between adjacent horizontal baffles.
Preferably, the filter chambers are welded and sealed with other adjacent filter plates except the filter chamber door.
The invention has the beneficial effects that:
1. according to the invention, the filter chamber door which is opened and closed is arranged on one side of the filter chamber, and the filter chamber is opened and closed through rotation, so that filter-pressed mud cakes in the filter chamber can be quickly poured out, and a large amount of labor cost is solved. Meanwhile, the filter medium is directly installed in the filter chamber of the filter press by changing the installation mode of the filter medium in the filter chamber of the filter press, so that the problem that the filter medium is fixed in the filter chamber through a partition plate in the prior art is solved, and the manpower required in the process of replacing the filter medium is reduced.
2. The invention is used for the filter press device, increases the filter pressing effect of the self weight of the sludge, increases the openable filter chamber door on the side surface of the filter chamber, reduces the labor intensity of workers and improves the working efficiency. The filter press with the structure can realize filter pressing operation without a partition plate, reduce the time required for replacing a filter medium and improve the working efficiency of the filter press; meanwhile, only filter cloth is loaded in the filter chamber, so that the efficiency of replacing the filter medium after a single working period is finished is improved, the labor intensity of workers is reduced, and the manufacturing cost of the filter press is reduced.
